    Corporation;

2.  Based on my knowledge, this Report does not contain any untrue statement of
    a material fact or omit to state a material fact necessary to make the
    statements made, in light of the circumstances under which such statements
    were made, not misleading with respect to the period covered by this Report;

4.  The Company's other certifying officers and I are responsible for
    establishing and maintaining disclosure controls and procedures (as defined
    in Exchange Act Rules 13a-15 (e) and 15d-15(e)) for the Company and have;

         a)   designed such disclosure controls and procedures, or caused such
              disclosure controls and procedures to be designed under our
              supervision, to ensure that material information relating to the
              Company, including its consolidated subsidiaries, is made known to
              us by others within those entities, particularly during the period
              in which this Report is being prepared;

         b)   evaluated the effectiveness of the Company's disclosure controls
              and procedures and presented in this Report our conclusions about
              the effectiveness of the disclosure controls and procedures, as of
              the end of the period covered by this Report based on such
              evaluation; and

         c)   disclosed in this Report any change in the Company's internal
              control over financial reporting that occurred during the
              Company's most recent fiscal quarter that has materially affected,
              or is reasonably likely to materially affect, the Company's
              internal control over financial reporting.

5.  The Company's other certifying officers and I have disclosed, based on our
    most recent evaluation of internal control over financial reporting, to the
    Company's auditors and the audit committee of the Company's board of
    directors:

         a)   all significant deficiencies and material weaknesses in the design
              or operation of internal control over financial reporting which
              are reasonably likely to adversely affect the Company's ability to
              record, process, summarize and report financial information; and

         b)   any fraud, whether or not material, that involves management or
              other employees who have a significant role in the Company's
              internal control over financial reporting.
